Cph1 was contained in a 5% sucrose solution and absorbance spectra recorded after photoexcitation with a laser pulse centred at ∼590 nm. (A) Transient absorption difference spectra at delay times of 1, 5, 10, 29, 60, 299, and 988 ps after excitation. (B) Kinetic transient at 673 nm (black squares) with a fit of the data to 2 exponentials shown in red.
